IMPROVED APPARATUS FOR THB MANUPAGTURB 01:'I VINEGAR.

ro ALL wHoM IT MAY ooNcERN:

Be it known that I, THEODORE GRUNDMANN, of Cleveland, in the county of Cuyahoga, and State of Ohio7 have invented a new and useful Improvement in Filtering and/'inegar-Apparatus; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the ari; to make and use the same, reference being had to the accompanying drawings, forming part of this speciiication, in which- Figure 1 represents a side elevation of my' improved iiltering-apparatus.

Figure 2 is a vertical central section of the same.

Figure 3 is a plan or top view, partly in section, of the same.

Figure 4 is a detail vertical section of the automatic mash-.distributer in the vinegar-apparatus.

Similar letters of reference indicate correspondingparts.

This invention relates'to a new apparatus for making vinegar from suitable fermented liquids.

It consists.iirst, in substituting, for the shavings gcnerallyvemployed, braided straw. cotton or hemp strings, which are held suspended,and along which the liquid has to tlow down 1n small streams.

The invention consists, second, in the construction and arrangement of an automatic distributor, which is a pivoted box, divided into two compartments. 'The liquid Hows into one compartment, and its weight, when it has filled such'compartment, swings the box around the pivot, so as to bring the other empty compartment'under the supply-pipe, while that previously lled is emptied into the apparatus.

The invention also consists in the construction of the whole apparatus, which can be easily taken apart.

and put together.

The invention consists, finally, of a lter, through which thermash is passed,preparatory to its passage to.

the vinegar-apparatus.

A, in the-drawing, represents a box or case, made ot wood,A or other suitable material, ofprismatic form, open at both ends, z'. e., at the upper and lower ends. v

'This boxis constructed b y connecting its sides, by means of hooks a a, or their equivalents, in such manner that it can be readily taken apart.

The box is s et upon a vessel, B, for receiving the liquid, and for closing its lower end.

Within the box A is set up or arranged a frame, C, which may, if desired, vbe simply a frameof slats, resting onlugs that project from the inner sides of the box, or which may be provided withlegs 6 b, as shown.

From the slats of the frame C is suspendeda series of braided strands, D D, which are either made of straw, ilax, hemp, or other suitable material, as is clearly. shown in fig. 2. I

Upon the frame C is placed awoven sheet, E, made of straw, or other material, or any other suitable porous fabric.

Above the sheet E is arranged, within the box A, a perforated horizontal plate, F, as shown in figs. 2 and 4. From this plate F project upward two lugs c e, which support a swinging box, G.

The box G is pivoted between and to'the lugs c, and is composed of two equal triangular compartments cl e, asin iig, 4, that are open ontop. l

If the box is turned to one side, so that the outer wall of the compartment e rests on the plate F, as in fig. 4, the other compartment d will be in position to receive the liquor, which is brought to it through a pipe ,f, from the filter H, said pipe discharging the liquor into a funnel, g, formed on the covering-plate L ofthe box A.

When-the compartment d has been filled, its weight causes the box G to turn over, so as to bring the other compartment e under the funnel, while. .the contents of d will be poured over the plate- F, whence they pass through the sheet E, and then flow gradually down the strands D. On these strands, the liquid is exposed to a draught of air, which enters the lower part of' the box A, through a pipe, z', and the liquid is thus, in small streams, that ow slowly along over and through the windings of the strands, amply oxygenated.

The liquor`thus acidiied is drawn oif the vessel B through a pipe, j;

The draught'and temperature in the box A can be regulated by means of dempers k k. By having the box G automatically operating, as described, the liquid will not be continuously discharged into the apparatus, but there will be, after a. portion has been emptied from a compartment, d or e, some time left for the liquid to clear the plate F, and sheet E.

The iilter H is a vessel, of suitable size and shape, provided with two perforated false bottoms, Zand m, between which saw-dust, shavings, or other equivalent material is compressed. The mash is poured upon the upper plate Z, has then to work through the lling, and through the plate m, and arrives in the lower compartment n of the filter, whence it is,'through the pipe f, conducted to the hopper.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent- 1. The braided strands D D, when used in a. vinegar-apparatus, for spreading the mash, and exposing it to the air, as set forth. Y

2. The self-regulating swinging mash-distributing box G, arranged substantially as herein shown and described. Y

3. The box A, when composed of a series of detachable plates, as set forth, so that the suspended braids D may be exposed to the air to be dried. i

4. A'vinegar-apparatus, consisting of the box A, vessel B, frame C, braided pendants D, distributing-box G, and supplyand discharge-pipesf and j, al1 made and operating substantially as herein shown and described.

5. The device set forth in the-foregoing clause, in combination with the lter H, in which the two perforated plates l and mare arranged, as set forth.

6. The distributing-sheet E, arranged between the swinging box G and the braided pendants D, substan.

tially as herein shown and described.

THEODORE GRUNDMANN.
